Spanner holes 44 in the angular 11 designates-a valve casing or box composedof an head 41 provide means for turning-or adjusting -upper portionl2'having'a fluid pressure chamber same, when desired.- I Q The function and general manner of operation of the device has been in large measure indicated from the foregoing description, it being understood, that the present valve assembly is attached by the threaded stem 17 to any convenient outlet of a source of compressed air or fluid controlled in any suitable manner, either automatic or manual, the compressed fluid being admitted when desired into the interior of chamber 13 through the openings 29, in the valve stem guide or plate 28. Assuming the chamber 15 is filled with adhesive and that compressed airor fluid has been admitted into the chamber '13, the spring-loaded plunger which includes the valve stem 22 and valve heads 21 and 41 will descend, and thus move the valve heads 21 and 41 from their respective seats in the passages 19 and 38, thereby permitting the adhesive in chamber 15 to be ejected through the now open passage 38, it being observed that the flap valve 37 has functioned to close the hole 34 during the ejecting period. When the contents of chamber 15 have been ejected, glue or other suitable adhesive will again be permitted to flow by gravity, or under pressure, through pipe 32, hole 34, againstthe flexible flap 37 which will now be deflected to admit the adhesive until the chamber 15 is filled anew. The chamber 15 it is tobe understood, while not permitting the escape of the adhesive l therefr'om, until the valve head 41 descends,

from the spirit or essential attributes thereof,

and I therefore desire the present embodiment to be considered in all respects as illustrative and not restrictive, reference being had to the appended claims rather than to the foregoing description .to indicate the scope of theinvention.

What I claim is:

1. A device of the kind described, comprising a casing composed of two parts, one of said parts having a chamber formed therein and adapted /:to admit fluid under pressure, a partition having a shoulder thereon arranged in said chamber, a spring seated on said shoulder, another of said parts having a chamber formed therein, said chamber being adapted to contain adhesive, an

Adhesive-admitting inlet arranged in said lastmentioned chamber, a flap normally closing said inlet but admitting adhesive into the adhesivecontaining chamber when desired, and valveoperated 'means for normally closing the ad hesive-containingchamber, but yielding to fluid admitted through thefirst-mentioned chamber under pressure, whereby a predetermined amount of adhesive may be ejected from the ad hesive-containing chamber.

f. 2. Anadhesive-depositing device of the kind described, comprising in combination, a casing, a pair of chambers formed in said casing; a partition arranged between said chambers, an open ing formed in said. partition, a yieldingly mountled valve member seating in and adapted to open and close said opening, an inlet for admitting adhesive in one of said chambers, a valve normally closing said inlet, and an outlet in said last-mentioned chamber for permitting the 'iescape of adhesive therefronnsaid, outletbeing combination of a casing adapted to be operably connected .to a source of fluid under pressure, a plurality of chambers provided in the casing, a valve stem movably mounted in said chambers and having a plurality of valve heads, a plurality of passages formed in said casing and communicating with said chambers, said valve heads coacting with said'passages to open and close same, spring means engaged with said stem and casing, an inlet formed in the casing, said inlet communicating with one of said chambers and a source of adhesive, and a flap valve normally closing said inlet but adapted to open same to l admit adhesive when said last-mentioned chamber is unfilled, whereby when said valve stem is moved by fluid under pressure acting on one of the valve heads, all of said valve heads will be actuated and adhesive contained in one of the chambers will be ejected therefrom.

5. In a device of the character described, the combination of a fluid pressure chamber and a communicating adhesive containing chamber,

valve means normally closing one of said chambers but operable by fluid under pressure when admitted to another of said chambers, inlet and outlet openings formed in said adhesive containing chamber, a flap valve yieldable to adhesive forced i into said first-mentioned chamber through said inlet opening, but closing said inlet opening when adhesive contained in said chamber is forced out by said fluid under pressure, said outlet opening permitting the escape of air from the adhesive containing chamber when adhesive is forced therein, and allowing adhesive to escape when 7 the valve means are actuated by fluid pressure.

6. In a device of the characterdescribed, the

combination of a fluid pressure chamber and a i engaged with the said valve means for normally retaining them in position for closing said cham-.

bers but permitting them to yield to fluid under pressure admitted to the fluid pressure chamber,

and inlet and outlet means connected to the last mentioned chamber, said inlet means being operable for admitting adhesive to the last-mentioned chamber, but preventing same from escaping through said inlet means, said outlet means permitting the ejection of adhesive from the chamber adapted to contain adhesive.

'7. In a device of the kind described, a casing, a chamber formed in said casing, said chamber being adapted to contain adhesive, a valve stem arranged in said casing, valve members secured on the stem, openings in the said chamber,;said openings being adapted to be opened and closed by said valve members, a third opening formed in the chamber, and serving to admit adhesive, a check valve normally closing said last-mentioned opening, one of said first-mentioned valve members serving to admit fluid under pressure to scribed, comprising a casing,a pair of chambers pair of chambers for operating both of said valve members, whereby adhesive will be ejected from the device.

9. In a device of the kind described, a chamber having an air inlet valve, an exhaust valve arranged to be operated by movement of the air valve, a spring arranged to normally close the air valve, an inletfor liquid adhesive, and a check valve for the said inlet.
